Generalization of electric charge adding color charge , mass-energy , etc.; sometimes considered same as its charge quantum number
In physics, a charge is any of many different quantities, such as the electric charge in electromagnetism or the color charge in quantum chromodynamics. Charges correspond to the time-invariant generators of a symmetry group, and specifically, to the generators that commute with the Hamiltonian. Charges are often denoted by, and so the invariance of the charge corresponds to the vanishing commutat... Wikipedia
